Patented Q'ct. 1, H 29 maze JOHN C. BROOKS, OF PATERSON, NEW JERSEY TEXTILE-FABRIC STRUCTURE Application filed June 28,

This invention relates to textile fabrics and particularly to a fabric of the so-called leno type, which is a fabric in which the Warp threads are interlaced with each other.

5 In my improved fabric the warp threads are arranged in groups of three, two warp threads of each group being standard or ground warp threads and the other being a douping warp thread.

10 In the weaving of the fabric the douping warp thread of each group is interlaced with both of the ground warp threads of said group, the interlacing being with both ground warp threads simultaneously after every third pick and with each warp thread alternately after the other picks. This produces a so-called leno fabric which is capable of being put to a wide variety of uses dependent upon. the character and size of the Warp threads.

The drawing shows more or less diagrammatically and on a greatly enlarged scale a fabric embodying my invention.

In the drawing the warp threads are inclicated at 1, 2 and 3. These threads are arranged in groups of three, the different groups being indicated at A, B, C, etc. Each group of three warp threads comprises two ground warp threads 1 and 2 and a douping 3c warp thread 3. The weft or filling thread is indicated at 4: and in the particular fabric shown these filling threads are double threads, there being two filling threads for each pick.

This, however, is not essential to the invention as it is equally applicable to a fabric in which there is a single filling thread for each pick. The question as to whether there will be one i or two filling threads for each pick depends upon the character of fabric desired.

The ground warp threads 1 and 2 pass over all the filling threads while the douping warp thread 3 passes under all the filling threads as usual in leno fabrics. In my improved fabric, however, the douping warp thread 3 passes over and is interlaced with first one and then the other of the two ground warp threads 1 and 2 after each of two successive picks, and after the third pick it crosses over so and is interlaced with both of the ground 1928 Serial 1%. 288,867.

warp threads and is thus returned to its normal position. a

For the sake of more clearly describing the invention the differentpicks are indicated on the drawings as pick 1, pick 2,, pick 3, pick 4, pick 5, pick 6, etc., said picks being shown as regularly spaced. After pick 1, or between pick 1 and, pick 2 the douping warp thread 3 crosses over the ground warp 1 as shown at 5. After this crossing the douping warp thread 3 passes under the filling threads of pick 2 while the ground warp threads pass over said filling. Between pick 2 and pick 3 or after pick 2 thedoup ing warp thread 3 passes over and is interlaced with the other ground warp thread '2 as shown at 6 and the douping warp thread then passes under the filling threads of pick 3 while'both ground warps pass over said fillingthread.

Between pick 3 and pick 4 the douping warp thread crosses over and is interlaced with both of the ground warp threadsl and 2 as shown at 7 a and the douping warp thread then passes under the'filling threads of pick t whilejboth ground warp threads pass over said filling threads. Between pick l and pick 5 the douping warp thread passes again over and is interlaced with the, ground warp thread 1 as shown at 5 while between picks 5 and 6 said douping warp thread passes over and is interlaced with the ground warp thread 2 as shown at 6 and between picks 6 and 7 said douping warp thread passes over and is interlaced with both ground warp threads again as shown at 7, this procedure being repeat-ed throughout the fabric.

The douping warp thread, therefore, passes over and is interlaced with both ground warp threads after every third pick and passes over and is interlaced with each of the other ground warps in turn after the other picks 5 and pick 6 while the ground warp thread 2 floats over picks 1 and 2 and picks 4 and'5. Each ground warp, therefore, is interlaced twice with the douping warp for each three picks and the interlacing of each doup thread with the two ground warp threads of the group has a staggered relation so that the two ground warp threads of any group float over different pairs of adjacent picks.

I claim:

1. A woven fabric having warp and filling threads in which the filling threads are arranged in uniformly spaced picks and the warp threads are divided into groups of three, each group comprising two ground warp threads and a douping warp thread, the douping warp thread of each group being interlaced with both the ground warp. threads after every third pick and with one ground warp thread only after each of the other picks. I

2. A woven fabric having Warp and filling threads in which the warp threads are dividedinto groupsot three, each group comprising two ground warp threads and a douping warp thread, the douping warp thread ofeach group being interlaced twice with each ground warp thread for each three consecutive picks, the ground warp threads passing overall the picks and the douping warp thread passing under all the picks.

3. A woven fabric having warp threads and filling threads in which the warp threads are divided into groups of three, each group comprising two ground warp threads and a douping warp thread, the douping warp thread of'each group being interlaced with both the ground warp threads after every third pick and with first one and then the other of the ground warp threads-after the other picks. v 4. A woven fabric comprising warp threads and filling threads in which the warp threads are divided into groups of three, each group comprising two ground warp threads and a douping warp thread, each ground warp thread floating over two of each group of three consecutive picks and being interlaced withthe douping warp thread each side of the third pick-of the group.

5. A woven fabric comprising warp threads and filling threads arranged in uniformly spaced picks, the warp threads being divided into groups of three, each group comprising two ground warp. threads and a douping warp thread, the ground warp threads passing over all of the picks and the duping warp threads passing under all the picks, the douping warp thread of each group beinginterlaced with both the ground Warp threads after every third pick and with one ground Warp thread only after each of the other picks.
